Strain Measurement in the Depth of the Order of Millimeter Using High Energy White X-rays [PDF]

, 2006
The strain in the bulk of material was evaluated using high energy white X-rays from a synchrotron radiation source of SPring-8 in Japan. An austenitic stainless steel (JIS-SUS304L) was used for a specimen. The specimen of 5 mm thickness was subjected to

Galactic x rays and gamma rays [PDF]

, 1969
A consistent explanation of the observed galactic flux of high-energy γ rays and the reported galactic x-ray flux is provided in terms of Compton scattering of cosmic-ray electrons with the submillimeter radiation observed recently.
